wood pulp, and which, when set up, may be relied upon to retain certain liquld or vislines.

cous materials without leakageand without liability to accidental collapse, wholly or partially, intoits knock-down state.

My boxes are especially, but not exclu sively, adaptable to the purpose of containlard or the like commodities in small parce s.

In the accompanying drawing, which forms a part of this application, Figure I is a plan view of one of my boxes in itskn'ockdown or perfectly fiat state. The lines of the creasings of the box, along which it is bent to set itu in shape, are indicated by dotted ig. II is a perspective view, of the box shown in I set up, but on a slightly enlarged scale, one of the cornersofthe box being to on to show, by comparison with the next atig'acent corner, the manner in which the corner structure is contrived and effected.

Referring to the numerals on the drawing, 1 indicates the bottom portion" of the box blank shown in Fi I. It may be of any referred shape, suc as the oblong rectang'uar shape illustrated, and of an preferred dimensions. With this bottom a l the members of the box form are made integral, as of a pliece of card board or wood ulp, as specified.

pon one side, it is provi ed .with a frontpiece 2 and upon the opposite side with a side-piece 3, from which extends a top 4 terminating, preferably, in a flap 5.

6 indicates one end-piece and 7 the other, the former being provided with a corner assembling-flap 8, and the latter with a corre-fj spondin member 9.

10 in icates the creasing-line which separates the bottom 1 from the side-piece 2, and 11 a creasing-line separating the bottom 1 from the side-piece 3.

12 and 13 indicate creasing-lines between the bottom and the end-pieces 6 and 7, respectively.

14 and 15 indicate the creasing-lines. be tween the end-pieces 6 and 7 and their assembling flaps 8 and-9, res ectively.

16 indicates a creasingine between the side-piece 3 and the top 4, and 17 a creasingline between the top 4 and its flaps.

Between each end-'piecefi and 7, and the side-pieces 2 and 3,.respectively, at each Patented. DOG- 1, 190s:

corner of the box is provided a corner-fold, of

which there are four. ing substantially identical in princi le of con- Each corner-fold be-" struction, it is sufiicient to ldenti y each of J them as defined by corner-creasing lines 19 and 20 and an intermediate creasin dine-21;

Each corner 'of the box form is s own as rovided with a wing, severally designated y the numerals 22, 23, 24, and 25. These several wings constitute, in effect, oblique extensions of the side-pieces 2 and 3, re-[ spectively, and it is characteristic of them that In the set up box, as illustrated in of'the ox substantially to the opposite cornor of the assembling-flap, to WhlOh they are connected in the set up box. securing the win 26 cut in the material of one member, for

instance the flap, and inserted into a slit 27 in the other'member, which, in the correlation specified, is formed in a wing.

construction of the wings and for their crossing over from one side of the box to the other, a specially strong and stable construction in the set up box is eflected. Not only do the win act as stay pieces for the corners, but 'w en bent over along their respective creasing-lines 28 to conform to the creasing-lines 14 and 15, respectively (compare Figs. I and II) the one'next to the assembling-fiap 8 or 9, as the case may be, being secured by its tongue 26, is also secured by the wing which over-laps it; and that, being secured by its tongue 26, is, in turn, secured by the superimposed top 4, which is provided in its flap 5 with a slit 30 into which the tongue 31 of a retaining-member 32, secured to the front-piece, is introduced and bent down to hold the parts together. The retaining-member 32 is preferabl made of soft flexible metal, the tongue 0 which to their respec sembhn'gfiap Pre erably consists of tongues] Y "15 3 II, the cross over obliquely from one conifer The means for 8 5 By reason of the relative dimensions and as required without breakage.

It will be observed from the foregoing specification that the wings 22 to 25, incluslve, constitute in connection with the assembling-flaps 8 and 9 the assembling-members of the set up box, and that each assembling-member in my construction is provided with not less than two distinct means for confining it in place for the performance of its oflice. For instance, referring to Fig. II, the wing 23 is directly confined by its tongue 26 and by the wing 22. In like manner, the Wing 25 is, in the fully set up box, confined by the wing 24. Now the win s 22 and 24, respectively, are not only con ed by their respective tongues 26, but are severally confined, when the box is closed, by the to 4. r

l 3y reason of the construction described, the assembling-flaps 8 and 9 being preferably formed to collectively cover substantially the entire contents contained within the assembled box, the box, when made up, filled and closed, afl'ords a strong, durable, cleanly, and nonleakable receptacle for a variety of commodities, such, for example, as lard or the like.

The material of the box is preferably saturated or coated on the inside with paraffin to render it hygienic and impervious to such liquids as may be introduced into it.

'For convenience of definition, it ma be specified that each corner of the boxorm.

shown in Fig. I is, in respect to the creasinglines which define the boundaries, trapezitorm in outline. The creasing-line 21 constitutes a diagonal of each trapezium along which the form may be folded in shaping the corner and to bring all of the parts of the corner structure into proper relative position.

What I claim is:

1. In a'knock-down box made of a sheet of flexible mate; ial, the combination with integrally united bottom, sides, ends, topand cozneufolds, of corner-assembling-flaps extending half way across the top of the box respectively, and means to secure to the respective flaps corner-folds adjacent thereto. 2. In a knock-down box made of a sheet of flexible material, the combination with integrally united bottom, sides, ends, top and corner folds, of corner assemblin flaps, wings upon the respective corner-folds each crossing obliquely from the corner of the box upon which itis located to the opposite corner of the assembling-flap to which it is secured, and means for securing the wings and corner assembling flaps respectively, together. I 3. In a knock-down box made of a sheet of flexible material, the combination with integrally united bottom, sides, ends, top, and

corner folds, of corner assemblin flaps, wings upon the respective corner-f0 ds each crossing obliquely from the corner of the box upon w hich it is located to the opposite corner of the assembling-flap to which it is secured, and two distinct means for confining each wing in place when the box is closed.

4. In a knock-down box made of a sheet of flexible material, the combination with integrally united bottom, sides, ends, top, and corner folds, of corner assemblin flaps, wings upon the respective corner-f0 ds each crossing obliquely from the corner of the box upon w hich it is located to the opposite corner of the assembling-flap to which it is se-- cured, and means for securing the wings and corner assembling flaps, respectively, said means consisting of integrally engaging slits and tongues formed in the material of which the box is made.

In testimony whereof I have hereunto signed my name in the presence of two subscribing witnesses.
